Description

Technical Field

[0001] The utility model relates to a honeycomb curtain with adjustable balance of a lower beam. Background Art

[0002] Honeycomb blinds are widely used because of their adjustable light function. Ordinary honeycomb blinds usually use electric or hand-pulled cords to raise and lower the curtains. After the cords at both ends have been used for a period of time, the balance of the lower beam of the honeycomb blind will shift due to inconsistent tightness. Once the lower beam shifts, it will not only look bad in terms of visual aesthetics, but also cause the lower beam to jam when moving in the tracks on both sides, causing a lot of inconvenience to the user. Therefore, a honeycomb blind that can adjust the balance of the lower beam is needed. Utility Model Content

[0033] (Example 1)

[0034] See Figure 1-6The honeycomb curtain with adjustable balance of the lower beam in this embodiment comprises an upper beam 1, a lower beam 2, a side track 3 and a circulating pull rope 4. A driving device and two rope reel groups are arranged in the upper beam 1. The two rope reel groups are respectively located on both sides of the driving device. The driving device is connected to the rope reel group in a transmission manner. In this embodiment, a tubular motor is selected for the driving device. The rope reel group comprises a first rope reel 5 far away from the driving device and a second rope reel 6 close to the driving device. Both ends of the circulating pull rope 4 wound around the first rope reel 5 and the second rope reel 6 pass through the curtain fabric. A pull rope fastener 7 is fixedly arranged at the bottom end of the side track 3 and the lower beam 2. A rotating shaft 7-1 is arranged in the pull rope fastener 7. In this embodiment, four pull rope fasteners 7 are arranged in the lower beam 2. With the center of the lower beam 2 as the boundary, two are arranged on one side, corresponding to the positions of the first rope reel 5 and the second rope reel 6, respectively. An adjusting component 8 is provided at the end of the lower beam 2. One end of the circulating rope 4 is wound around the first rope reel 5, and the other end is passed through the rotating shaft 7-1 in the rope fastener 7 corresponding to the first rope reel 5 in the lower beam 2, passes through the adjusting component 8, passes through the rotating shaft 7-1 of the rope fastener 7 in the side track 3, passes through the adjusting component 8, passes through the rotating shaft 7-1 in the rope fastener 7 corresponding to the second rope reel 6, and then is wound around the second rope reel 6. The rotation directions of the first rope reel 5 and the second rope reel 6 are opposite. The adjusting component 8 adjusts the tightness between the lower beam 2 and the circulating rope 4. When the lower beam 2 is fixed to the circulating rope 4 through the adjusting component 8, the driving device drives the first rope reel 5 and the second rope reel 6 to drive the lower beam 2 to slide in the side track 3. When the lower beam 2 is loosened from the circulating rope 4 through the adjusting component 8, the balance of the lower beam 2 can be adjusted.

[0035] See Figure 4 The adjustment assembly 8 includes an adjustment side cover 8-1, an adjustment screw 8-2 and a clamp 8-3. A fixing plate 8-1-1 is provided in the adjustment side cover 8-1. The fixing plate 8-1-1 divides the adjustment side cover 8-1 into two cavities. Both ends of each cavity are provided with wire holes for the circulation rope 4 to pass through. The circulation rope 4 passes through the adjustment assembly 8 twice in opposite directions and from different cavities. The circulation rope 4 passes through the adjustment side cover 8-1 in a direction parallel to the fixing plate 8-1-1. The fixing plate 8-1-1 and the clamp 8-3 clamp the circulation rope 4. The adjustment screw 8-2 adjusts the distance between the clamp 8-3 and the fixing plate 8-1-1. When the balance of the lower beam 2 needs to be adjusted, the adjustment screw 8-2 is loosened to release the circulation rope 4. After the adjustment is completed, the adjustment screw 8-2 is tightened again to re-clamp the circulation rope 4.

[0036] The side of the fixing plate 8-1-1 facing the clamp 8-3 is a toothed surface, which increases the surface friction. The end of the clamp 8-3 cooperates with the fixing plate 8-1-1, making it more stable when clamping the circulating pull rope 4.

[0037] The adjusting component 8 is also provided with a roller 8 - 4 , and the circulating pull rope 4 bypasses the roller 8 - 4 when passing through the adjusting component 8 , thereby reducing friction and making the circulating pull rope 4 move more smoothly at the adjusting component 8 .

[0038] See Figure 6 An adjustment panel 3-1 is provided on the side track 3, an adjustment slot is provided on the adjustment panel 3-1, and a detachable adjustment flap 3-2 is provided in the adjustment slot. When adjusting the balance of the lower beam 2, there is no need to disassemble the lower beam 2 or the side track 3. It is only necessary to control the lower beam 2 to stop at the adjustment panel 3-1, open the adjustment flap 3-2, and then the tightness of the adjustment screw 8-2 can be adjusted.

[0039] A horizontal adjustment mark 3-3 is also provided on the adjustment panel 3-1, which makes it easier to align the two ends and facilitates the user to adjust the balance.

[0040] The utility model adopts a circulating pull rope 4 and sets an adjustment component 8 to adjust the tightness between the lower beam 2 and the circulating pull rope 4. When the lower beam 2 deviates, the tightness between the lower beam 2 and the circulating pull rope 4 is readjusted to adjust the balance of the lower beam 2.

[0041] (Example 2)

[0042] See Figure 5 The difference between this embodiment and embodiment 1 is that an elastic member 7-2 is also provided in the pull rope fastener 7. In this embodiment, the elastic member 7-2 is a spring, one end of the spring is fixed to the pull rope fastener 7, and the other end is fixed to the rotating shaft 7-1. The spring and the rotating shaft 7-1 cooperate to tension the circulating pull rope 4.

[0043] (Example 3)

[0044] The difference between this embodiment and embodiment 1 is that two pull rope fasteners 7 are provided in the lower beam 2, and the pull rope fasteners 7 correspond to the position of the second rope reel 6. The circulating pull rope 4 is wound at one end of the second rope reel 6 and passes through the curtain fabric, and is wound at one end of the first rope reel 5 and is routed directly through the side track 4.

[0045] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
